CCS3.3非标准位域出现的警告，附程序

编译器如何设置可以消除这种警告呢？

            struct CMD_BITS
            {                                     // bit description
LINE:45    UINT32      Bfa:10;         // 10 Don't care bits/BufferAddess bits
LINE:46    UINT32      PageAddr:12;// 12 Page Addr bits
LINE:47    UINT32      Rsvd2:2;         // 2 Don't care bits
LINE:48    UINT32      OpCode:8;      // 8 Op Code bits
            };
            struct CMD_WORD
            {
LINE:53    UINT32       low:16;
LINE:54    UINT32       high:16;
            };
            union AT45_CMD
            {
                structCMD_WORDword;
                structCMD_BITSbit;
            };
